Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a tabletop water purifier. Background Technology

[0002] With the development of the times, people have increasingly higher requirements for drinking water quality, and water purifiers have been widely recognized and purchased. Water purifiers can purify tap water or water in a water tank to provide users with high-quality clean water. Water purifiers on the market include built-in water purifiers, under-sink water purifiers, and countertop water purifiers. Countertop water purifiers have become a popular choice due to their ease of use.

[0003] Countertop water purifiers typically have a water tank to store raw water. Therefore, they can be used in locations without a tap water source, such as restaurants or bedrooms. Water purifiers that provide cold water have an internal cooling system. This cooling system needs to dissipate heat during the cooling process, so existing cold water purifiers usually have a fan to provide sufficient airflow for cooling.

[0004] Because air has a very low specific heat capacity, the air temperature around the cooling components rises rapidly under the same cooling power. A large volume of air needs to be pumped around the cooling components by a fan to ensure they maintain good heat dissipation. However, fans capable of pumping large volumes of air are noisy, resulting in a poor user experience. Utility Model Content

[0005] To at least partially address the problems existing in the prior art, some embodiments of this utility model provide a countertop water purifier with a main water outlet, including: a filter assembly having a raw water outlet and a purified water outlet; a water storage tank, the raw water outlet being connected to the water storage tank via a raw water pipeline, a booster pump being installed on the raw water pipeline; and a cold tank, the cold tank including a cold water chamber, a refrigeration assembly, and a first water-cooling assembly, the inlet of the cold water chamber being connected to the purified water outlet via a water supply pipeline, and the outlet of the cold water chamber being connected to the main water outlet, wherein: the cold end of the refrigeration assembly can exchange heat with the cold water chamber, and the hot end of the refrigeration assembly can exchange heat with the first water-cooling assembly; and the inlet of the first water-cooling assembly is connected to the water storage tank via a first water-cooling pipeline, the outlet of the first water-cooling assembly is connected to the water storage tank via a second water-cooling pipeline, and a circulation pump is installed on at least one of the first water-cooling pipeline and the second water-cooling pipeline. Water cooling of the refrigeration components via a water tank efficiently removes heat generated and transferred by the components. The water tank also provides a convenient source of cooling water, enabling highly efficient cooling. Water cooling significantly reduces noise levels during operation. At a distance of 20cm from the refrigeration components and with a background noise level of 30.9dB, water cooling can reduce noise to as low as 35.6dB, compared to 53.1dB for air cooling. This greatly improves the user experience. Water-cooled water purifiers do not have air vents, so there are no placement restrictions; they can be installed against a wall.

[0006] For example, the filtration assembly also includes a concentrate inlet, which is connected to the inlet of the first water-cooling assembly via a concentrate pipeline. The generated concentrate can further pass through the first water-cooling assembly to cool it before flowing back into the water storage tank. This reduces the number of openings in the water storage tank and simplifies its manufacturing process. Optionally, during water production, it may be possible to dissipate heat from the cooling assembly solely through the concentrate, without needing to activate the circulation pump.

[0007] For example, a check valve is installed on the concentrate pipeline. The check valve can prevent the raw water pumped by the circulating pump from flowing back from the concentrate pipeline to the concentrate outlet of the filter assembly under pressure when the booster pump stops working, thus avoiding affecting the performance and lifespan of the filter assembly.

[0008] For example, a circulation pump is installed on the first water-cooling pipeline, and the concentrate pipeline is connected to the second water-cooling pipeline, which in turn connects to the inlet of the first water-cooling component. In this way, the concentrate and the raw water can return to the water storage tank together through the circulation pump, thus preventing the two pressure sources from conflicting with each other and increasing the water flow through the first water-cooling component.

[0009] For example, it also includes a second water-cooling component. The hot ends of the second water-cooling component and the cooling component can exchange heat. The concentrate outlet is connected to the inlet of the second water-cooling component via a concentrate pipeline, and the outlet of the second water-cooling component is connected to a water storage tank. Thus, the concentrate generated during water production or the raw water used for rinsing can be cooled by the second water-cooling component, while the raw water pumped by the circulating pump can be cooled by the first water-cooling component. The flow rates of these components do not interfere with each other, resulting in optimal water cooling performance.

[0010] For example, a wastewater ratio solenoid valve is installed on the concentrate pipeline. The rapidly discharged raw water also prevents the filter assembly from producing purified water; all raw water can return to the storage tank via the concentrate pipeline and either the first or second water-cooling assembly under the action of the booster pump. In short, the water purifier can also flush the filter assembly using the wastewater ratio solenoid valve, and during the flushing process, it can provide water-cooled heat dissipation to the cooling assembly.

[0011] For example, the countertop water purifier also includes a purified water tank, which is connected in series on the water supply line. The purified water tank can store a large amount of purified water produced by the filtration assembly. When the user needs cold water, the purified water tank can replenish the cold water chamber with room temperature purified water. This avoids the need to start the booster pump to produce water every time the user needs cold water, reducing the number of times the booster pump starts and stops, extending the lifespan of the filtration assembly, and reducing the noise of the water purifier. In some embodiments, the filtration assembly has a low-flow-rate filter element (daily water production less than 400 gallons). In this case, the purified water tank can also temporarily store the produced purified water when the user is not using water, thus allowing a large flow of cold or room temperature water to be provided to the user. Furthermore, water cooling causes the water temperature in the storage tank to rise; the purified water tank ensures that the purified water replenished to the cold tank or the room temperature water provided to the user is at a relatively low temperature.

[0012] For example, a cold water pump is installed on the water supply line. This pump delivers cold water to a height above the cold water chamber or above the water level in the purified water tank, effectively increasing the water flow and improving the user experience. Furthermore, the cold tank is only connected to the outside environment via the cold water line. When the user needs cold water, the pump draws room-temperature purified water from the purified water tank to replenish the cold tank, forcing the cold water inside to the main outlet. Therefore, the cold tank does not have a vent for balancing air pressure, resulting in a simpler structure. By not connecting to the atmosphere through a vent, foreign objects, dust, and bacteria are prevented from entering the cold tank, making it less prone to bacterial growth and allowing for simple maintenance such as evacuation.

[0013] For example, the water tank is also connected to the main water outlet via an outlet pipe, on which a water pump is installed. The outlet pipe allows room-temperature purified water from the water tank to be supplied to the user. Similar to a cold water pump, the outlet pump also allows for unrestricted main water outlet height and provides a larger flow rate of room-temperature water.

[0014] For example, a heating element is connected in series on the water outlet pipe. Thus, the purified water at room temperature in the water tank can be heated by the heating element and provided to the user.

[0026] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0027] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0028] This utility model provides a countertop water purifier. The countertop water purifier according to an embodiment of this utility model will be described in detail below with reference to the accompanying drawings. Figure 1 As shown, the countertop water purifier has a main water outlet 10, which can provide filtered room temperature water. As mentioned above, the countertop water purifier includes a water storage tank 200, which can store raw water. The raw water includes, but is not limited to, tap water, bottled water, etc. Optionally, the user can remove the water storage tank 200 from the main body of the countertop water purifier, add raw water, and then install it back onto the main body of the countertop water purifier. The countertop water purifier may also include a filter assembly 100, which has a raw water outlet 101 and a purified water outlet 102. The filter assembly 100 may include a reverse osmosis filter, an ultrafiltration filter, a nanofiltration filter, or any two or more of these combined into a filter. Optionally, the filter assembly 100 may include a pre-filter and a central filter. The pre-filter may include activated carbon, polypropylene fiber (PP) cotton, porous ceramic filter, etc., or any two or more of these combined into a filter. It can be installed before the central filter cartridge to perform pre-filtration on the water entering the central filter cartridge, thereby extending the service life of the central filter cartridge.

[0029] The raw water inlet 101 is connected to the water storage tank 200 via a raw water pipeline 300, and a booster pump 310 can be installed on the raw water pipeline 300. The booster pump 310 can pump the raw water, which has almost no pressure in the water storage tank 200, to the filter assembly 100, giving it sufficient pressure to pass through the filter assembly 100 to produce purified water. The booster pump 310 can be, but is not limited to, a diaphragm pump, a rotary vane pump, etc. In embodiments where the filter assembly 100 uses a reverse osmosis filter element and a nanofiltration filter element, the booster pump 310 can provide a larger water pressure to meet the working pressure of the filter assembly 100.

[0030] The countertop water purifier may also include a cold tank 400, which may include a cold water chamber (not shown) disposed therein. Optionally, the cold water chamber may have a shape substantially the same as the main body of the cold tank 400, being cubic in shape. Optionally, the cold tank 400 may have tortuous pipes formed inside, with the cold water chamber having an inner cavity formed by the pipes, thereby increasing the inner surface area of ​​the cold water chamber. The cold tank 400 may also include a refrigeration component, which may include a compressor-type refrigeration component, a semiconductor refrigeration component, or other existing or future refrigeration components. Regardless of the type of refrigeration component, heat is generated during the refrigeration process, causing one part of the refrigeration component to form a hot end and the other part to form a cold end. The cold end of the refrigeration component can exchange heat with the cold water chamber, thereby cooling the water in the cold water chamber. The inlet of the cold water chamber is connected to the purified water outlet 102 via a water supply pipe 700, and the outlet of the cold water chamber is connected to the main outlet 10. Thus, the water purifier can provide users with cold water below room temperature. Optionally, the main water outlet 10 can be connected to a faucet or a water spout. Optionally, the main water outlet 10 can have multiple separate openings, so that water that has undergone different treatments, such as chilled water or heated water, can be provided to the user through different openings without interference.

[0031] For any existing type of refrigeration component, the refrigeration efficiency decreases when the temperature difference between its hot and cold ends is too large. Taking semiconductor refrigeration as an example, when the temperature difference between its hot and cold ends reaches more than 50 degrees Celsius, its refrigeration effect decreases significantly, causing the water temperature in the cooling tank 400 to hardly decrease any further, making it difficult for the water purifier to provide the required temperature of cold water. Therefore, the hot end of the refrigeration component needs to be cooled. The hot end of the refrigeration component can exchange heat with the first water-cooling component 410, which can transfer the heat from the hot end to the cooling water. Since water has a much higher specific heat capacity than air, the temperature rise of the same volume of water is much less than that of the same volume of air during the process of water passing through the first water-cooling component 410. In some embodiments, the refrigeration component includes a compressor and a refrigerant circulation pipeline. In this case, the first water-cooling component 410 can be constructed as nested pipelines, with one of the refrigerant and cooling water flowing in the inner tube of the first water-cooling component 410, and the other flowing between the outer wall of the inner tube and the outer tube. Optionally, the first water-cooling component 410 may include a heat sink and water pipes made of thermally conductive material embedded in the heat sink. Optionally, the first water-cooling component 410 may include a water cooling head. For a semiconductor cooler, since it does not have a pipe structure, the first water-cooling component 410 can be a planar component such as the water cooling head described above. Optionally, the first water-cooling pipe 420 or the second water-cooling pipe 430 may also be constructed as the first water-cooling component 410 or as part of the first water-cooling component 410, for example, at least a portion of the first water-cooling pipe 420 or the second water-cooling pipe 430 may be made of thermally conductive material and in contact with the hot end. Thus, only a very small flow rate of cooling water is needed to achieve the same cooling effect as a larger flow rate of air. Experiments show that, within a calibrated time, when the water is cooled to a preset temperature, the cooling power is 60W, the temperature difference between the cold water and the air is 10 degrees Celsius, and the required air flow rate is 279 L / min. With the same cooling power of 60W and a temperature difference of 5 degrees between cold water and cooling water, the required water flow rate is only 170mL / min.

[0032] The inlet of the first water-cooling component 410 is connected to the water storage tank 200 via the first water-cooling pipe 420, and the outlet of the first water-cooling component 410 is connected to the water storage tank 200 via the second water-cooling pipe 430. A circulation pump 440 is installed on at least one of the first water-cooling pipe 420 and the second water-cooling pipe 430. The circulation pump 440 may also include a suitable pumping device such as a centrifugal pump, diaphragm pump, or rotary vane pump. Since the raw water capacity of the water storage tank 200 is much larger than the amount of water to be cooled stored in the cold water chamber, in one specific embodiment, the volume of the cold water chamber is 500ml, and the raw water in the water storage tank 200 is typically 2L-5L. Taking a 2L water storage tank 200 as an example, with an ambient temperature of 19.6 degrees Celsius and a water temperature of 25 degrees Celsius in the water storage tank 200, it takes approximately 24 minutes to lower the water temperature in the cold water chamber to 5 degrees Celsius, ultimately resulting in a water temperature of 37.9 degrees Celsius in the water storage tank 200. Therefore, water cooling of the refrigeration components through the circulation of raw water in the water storage tank 200 can meet the usual needs and will not cause the temperature of the room temperature water used by the user to rise too much.

[0033] Water cooling of the refrigeration components via the water tank 200 efficiently removes heat generated and transferred by the components. The water tank 200 also provides convenient access to cooling water, enabling highly efficient cooling. Water cooling significantly reduces noise levels during operation. At a distance of 20cm from the refrigeration components and with a background noise level of 30.9dB, the noise level of water cooling is as low as 35.6dB, compared to 53.1dB for air cooling. This significantly improves the user experience. Water-cooled water purifiers do not have air vents, so there are no placement restrictions; they can be installed against a wall.

[0034] like Figure 2 As shown, exemplarily, the filter assembly 100 may further include a concentrate outlet 103, which is connected to the inlet of the first water-cooling assembly 410 via a concentrate pipeline 500. As described above, the filter assembly 100 may include a reverse osmosis filter element or a nanofiltration filter element, both of which produce a certain proportion of concentrate during the filtration process, and the concentrate is discharged from the concentrate outlet 103. Both of these filter assemblies 100 have good filtration performance and can provide users with high-quality purified water. The generated concentrate can further pass through the first water-cooling assembly 410 to cool the first water-cooling assembly 410 before flowing back to the water storage tank 200. This reduces the number of openings in the water storage tank 200 and simplifies the process of the water storage tank 200. Optionally, during the water production process, it may not be necessary to turn on the circulation pump 440; the cooling assembly may be cooled only by the concentrate.

[0035] like Figure 3As shown, exemplarily, the countertop water purifier also includes a purified water tank 710, which is connected in series with the water supply pipe 700. The purified water tank 710 can store a large amount of purified water produced by the filter assembly 100. When the user needs cold water, the purified water tank 710 can replenish the cold water chamber with room temperature purified water. This avoids the need to start the booster pump 310 to produce water every time the user needs cold water, reducing the number of start-stop cycles of the booster pump 310, extending the service life of the filter assembly 100, and reducing the noise of the water purifier. In some embodiments, the filter assembly 100 has a low-flow-rate filter element (daily water production less than 400 gallons). In this case, the purified water tank 710 can also temporarily store the produced purified water when the user is not using water, thereby allowing a large flow of cold or room temperature water to be provided to the user. Furthermore, water cooling causes the water temperature in the storage tank 200 to rise. Setting up a clean water tank 710 can ensure that the clean water supplied to the cold tank 400 or the room temperature water provided to the user is at a relatively low temperature.

[0036] For example, a cold water pump 720 can also be installed on the water supply pipe 700. The cold water pump 720 can pump cold water to a height higher than the cold water chamber or the liquid level in the clean water tank 710, which can effectively increase the water flow rate and improve the user experience. Furthermore, the cold tank 400 is only connected to the outside world through the cold water pipe. When the user needs cold water, the cold water pump 720 can draw room-temperature clean water from the clean water tank 710 to replenish the cold tank 400, squeezing the cold water in the cold tank 400 to the main outlet 10. Therefore, the cold tank 400 does not have a vent for balancing air pressure, resulting in a simpler structure. By not connecting to the atmosphere through a vent, foreign objects, dust, and bacteria can be prevented from entering the cold tank 400, making it less prone to bacterial growth and allowing for simple maintenance through methods such as evacuation.

[0037] For example, the water tank 710 is also connected to the main water outlet 10 via a water outlet pipe 800, on which a water pump 810 is installed. The water outlet pipe 800 can supply the user with purified water at room temperature from the water tank 710. Similar to the cold water pump 720, the water pump 810 also allows the height of the main water outlet 10 to be unrestricted and provides a larger flow rate of room temperature water.

[0038] For example, a heating element 820 is connected in series on the water outlet pipe 800. The heating element 820 may include, but is not limited to, existing or future heating elements such as a thick-film heating element 820, a hot water tank, or an electromagnetic heater. Thus, room-temperature purified water in the water tank 710 can be heated by the heating element 820 and provided to the user. Optionally, the water outlet pump 810 can control the flow rate, thereby enabling the water purifier to provide the user with hot water at a relatively accurate temperature.

[0039] In some embodiments, when the water storage tank 200 is at a high temperature, the booster pump 310 is activated to produce water, and the circulation pump 440 is also turned on to ensure the cooling effect. Figure 3 In the illustrated embodiment, the circulation pump 440 is mounted on the second water-cooling pipeline 430, and the concentrate pipeline 500 is connected to the second water-cooling pipeline 430 downstream of the circulation pump 440. When the circulation pump 440 is operating, the outlet water pressure of the concentrate pipeline 500 may affect the operation of the circulation pump 440. Conversely, the water pressure of the circulation pump 440 may also affect the water production of the filter assembly 100. Figure 4 As shown, exemplarily, the circulation pump 440 can be installed on the first water-cooling pipeline 420, and the concentrate pipeline 500 is connected to the second water-cooling pipeline 430, so as to connect to the inlet of the first water-cooling component 410 through the second water-cooling pipeline 430. In this way, the concentrate and the raw water can return to the water storage tank 200 together through the circulation pump 440, so that the two pressure sources do not conflict with each other, and the water flow through the first water-cooling component can be increased.

[0040] like Figure 5 As shown, by way of example, a check valve 510 may also be provided on the concentrate pipeline 500. The check valve 510 can prevent the raw water pumped by the circulation pump 440 from flowing back from the concentrate pipeline 500 to the concentrate port 103 of the filter assembly 100 under pressure when the booster pump 310 stops working, thus avoiding affecting the performance and lifespan of the filter assembly 100.

[0041] For example, the countertop water purifier may further include a second water-cooling component 600, the hot ends of which are capable of heat exchange with the cooling component. The concentrate outlet 103 is connected to the inlet of the second water-cooling component 600 via a concentrate pipe 500, and the outlet of the second water-cooling component 600 is connected to a water storage tank 200. In some embodiments employing semiconductor cooling, two or more semiconductor coolers may be provided on each cooling tank 400. Each semiconductor cooler may be matched with a water cooling head, where one or more water cooling heads may serve as the first water-cooling component 410, and other water cooling heads may serve as the second water-cooling component 600. The first water-cooling component 410 and the second water-cooling component 600 are respectively connected to the water storage tank 200 through different water paths, thereby avoiding excessively high water temperature at the last water cooling head due to multiple water cooling heads connected in series, or excessively low water flow rate for each water cooling head due to multiple water cooling heads connected in parallel. Optionally, the first water-cooling component 410 and the second water-cooling component 600 may be integrated, separated only by their water paths. Specifically, the first water-cooling component 410 and the second water-cooling component 600 may include heat sinks and cooling pipes disposed on the heat sinks. The first water-cooling component 410 and the second water-cooling component 600 may share the same heat sink. At least one of the two cooling pipes is connected to the first water-cooling pipe 420 and the second water-cooling pipe 430, and the other of the two cooling pipes is connected in series to the middle section of the concentrate pipe 500. Thus, the concentrate generated during water production or the raw water used for rinsing can be cooled by the second water-cooling component 600, and the raw water pumped by the circulating pump 440 can be cooled by the first water-cooling component 410. The flow rates of the two components do not interfere with each other, resulting in optimal water cooling performance.

[0042] In some of the above embodiments, during water purification or rinsing, concentrated water or the raw water used for rinsing can be used for water cooling. When water purification or rinsing stops, water cooling can be achieved solely through the circulation pump 440, thereby reducing the noise of the water purifier. In cases requiring rapid cooling or when the water temperature in the storage tank 200 is high, the booster pump 310 and the circulation pump 440 can work together to enhance the water cooling effect.

[0043] Under the pressure of the booster pump 310, the raw water passes through the filter assembly 100, and the ratio of the purified water to the remaining concentrated water that does not pass through the filter assembly 100 is the wastewater ratio. The wastewater ratio can be limited by, for example, the structure of a wastewater ratio valve. For example, a wastewater ratio solenoid valve 520 is provided on the concentrated water line 500. The wastewater ratio solenoid valve 520 may include a valve core with a small orifice, which can function as a wastewater ratio valve. When the wastewater ratio solenoid valve 520 is closed, it maintains the pressure required for the filter assembly 100 to operate and allows a certain flow rate of concentrated water to pass through it. When the wastewater ratio solenoid valve 520 is open, raw water can quickly pass through it from a passage other than the wastewater ratio valve, thereby flushing the filter assembly 100. The rapidly discharged raw water also prevents the filter element 100 from producing purified water. All the raw water can return to the water storage tank 200 through the concentrate pipeline 500 and the first water-cooling component 410 or the second water-cooling component 600 under the action of the booster pump 310. In short, the water purifier can also flush the filter element 100 through the wastewater ratio solenoid valve 520, and perform water-cooling heat dissipation on the cooling component during the flushing process.
